This seems like it should be a simple task but for some reason Postfix isn't rejecting email by using RBL lookups.
Here is my smtpd configuration: smtpd_recipient_restrictions = reject_non_fqdn_sender, reject_unknown_recipient_domain, reject_unauth_pipelining, reject_non_fqdn_recipient, reject_rbl_client sbl.spamhaus.org, reject_rbl_client xbl.spamhaus.org, permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination, permit_auth_destination, permit Can anyone see the reason why RBL lookups aren't happening? Thanks! Kaleb
